Air Spring Kit Specifications

The Firestone Coil-Rite rear air spring system supplements the factory rear coil springs with manually adjustable air support. Changing air pressure alters the spring rate, providing additional resistance under heavier loads and a softer suspension response when the vehicle is lightly loaded.

Overview

This air spring kit adds adjustable load support to the 1st-Gen Sequoia without replacing the coil spring setup. Installed within the factory rear coils, the air springs help accommodate additional weight from passengers, luggage, and equipment. Manual pressure adjustment lets drivers tailor rear suspension response to each trip's demands.

Support

A fully loaded cabin or cargo area can place additional demands on the rear suspension. The air springs provide supplemental resistance to help manage that added weight, reducing excessive sag and supporting a more level stance.

Performance

The kit system uses air pressure to change the amount of support provided by each spring. Higher pressure creates a firmer response when carrying heavier loads, while lower pressure allows a softer response during lighter use.

Adjustability

Separate air valves allow for independent adjustments. Drivers can add or release air using a standard inflation source, providing control over suspension firmness without requiring an onboard compressor or electronic controller.

Balance

The adjustable design helps support both loaded and unloaded operation. Additional support is available when the vehicle is carrying weight, while reduced pressure allows a more compliant response for everyday passenger travel.
